8 Claims. (Cl. 226-14) The invention relates to a mechanism for handling eggs and placing the same in cartons for merchandising, and the instant application forms a divisional of our pending application Serial No. 138,714, led January 16, 1950. The parent application was directed generally to a mechanism for handlingy eggs, including a means for receiving eggs from a supply and arranging the same in series, means for advancing the series either to a candler or directly to packaging means, by which latter the eggs are successively placed in the individual cells of cartons. The present divisional application while describing the complete automatic mechanism is directed more particularly. to the packaging means, and the invention consists in the general construction and certain specific features thereof, as hereinafter described.

In the handling of eggs preparatory to merchandising, they are preferably first graded as to size and are then placed in holders which are usually of dozen size fo"r retail sale, three-dozen size for wholesale and in some localities two and one-half dozen size.y At some point in the handling, the eggs are candle'd or inspected and those found defective are removed. The mechanism forming the subject matter of the instant invention is designed to handle eggs which may have been previously graded but not candled and, as above stated, it is the object to secure completely automatic operation from this point to the delivery of the filled cartons.

In general construction the machine comprises a table A on which eggs are irst deposited from any-suitable source of supply. As shown a conveyor belt A1 carries the eggs (preferably previously graded) across one end of the table A, and an inclined bar A2 transfers them from the belt onto said table. This tablerhas side rails A3 for retaining the eggs thereon and is further provided with a soft llexible cover sheet B on which the eggs 2,717,729 Patented Sept. 13, 1955 ICC rest. At one end of the table is a gate C which is intermittently operated to permit the passage of a single row of eggs and the depositing of the same upon an adjacent, longitudinally traveling conveyor. To maintain the eggs on the table in operative relation to the gate, they are slowly advanced by means placing only a slight pressure against the individual eggs so as to avoid danger of breakage. This advancing means consists in an endless conveyor D passing around sprockets D1 and having a series of bars or rollers D2 extending transversely across the table. The flexible sheet B rests upon the rollers D2 of the upper portion of the conveyor, which is traveling in the direction of the arrow or from the outer end of the table towards the gate C. As the sheet B is very flexible the eggs resting thereon will press it down between adjacent rollers and during advancement of the conveyor these rollers will propel the eggs forward. However, if thereis any obstruction such as an accumulation of the eggs adjacent to the gate, the pressure exerted by the conveyor is too slight to endanger breakage. ln other words, the eggs will be merely lifted and lowered as the rollers pass under the same, but whenever they are free to advance the forward pressure will be sufficient for this purpose. Some or all of the rollers D2 preferably have grooves D3 in the opposite and peripheral portions thereof with a helical shoulder at one edge of the groove for propelling the eggs from opposite sides towards the center of the table A. This is desirable for concentrating the eggs so as to leave no gaps in the series separated by the gate.

Row advancing means The gate C is preferably formed as shown in Fig. 8 and comprises a rotary shaft C1 journaled in bearings C2 at its opposite ends and having intermediate said bearings a plurality of radially extending anges C3. Normally one of said flanges is in a substantially horizontal plane at the end of the conveyor D to receive eggs therefrom. Another ange extends upward in the path of the eggs, so that it is only when the roller is rotated through an angle of or thereabouts that eggs` can pass the gate. Such rotation is controlled by means which will later be described, and it operates only when more eggs are required to complete a longitudinally advancing series. Such series is formed by successive rows of eggs removed from the table A and deposited on a traveling conveyor E. on the opposite side of the gate. The conveyor E comprises a pair of spaced, parallel, endless belts El, E2 having their upper strands extending in a horizontal plane slightly lower than the gate C so that the eggs in the row transferred by the gate will roll down onto the belts. The space E3 between the belts permits the eggs to` drop slightly therein so as to be supported by the belts on the opposite sides thereof. A rail E4 parallel to and onthe outer side of the belts retains the eggs from dropping off, and therefore the row or series will be advanced longitudinally thereof., Each of the spaced belts El, E2 will advance or turn an egg in contact therewith and this prevents any clogging which might otherwise occur when eggs are deposited by the gate C. A single central belt E5 extends forward from the belts El and E2 to continue the advancement of the series which might extend to the point where'the eggs are to be deposited in the cartons but preferably we interpose a Candler of the following construction.

A Candler F is an endless conveyor in alignment with the conveyor E, which is formed by spaced chains F1 having spaced hour-glass shaped rollers F2 extending therebetween. The eggs from the conveyor E will be deposited between pairs of adjacent rollers F2 and, during the forward progress of the upper strands of the chains F1, will `tbe :moved over the candler. This consists -of a box G Containing electric light bulbs G1, said box being open at the top for the passage of an upwardly directed beam of light centrally beneath .the row of eggs on the conveyor F. During the interval in which the rollers F2 Iarepassing over the box G, rotary motion is `intermittently imparted to these rol-1ers to spin .the eggs supported thereon. As shown .in Figs. 9 and 1.0, a `series of constantly rotating friction wheels F3 .are arranged beneath vthe portion of .the conveyor F which passes ,over thebox G. These wheels are in .the path of .cooperating friction wheels F4 at the .end of each roller F2 and are adapted inthe progress of ythe conveyor to raise each roller and impart rotary motion thereto while passing over the corresponding `friction roller F3. Asa result adjacent rollers vwill spin the egg supported therebetween while passing .over the friction wheels F3, but will cease to ro-tate during the intervals in which the friction wheels F4 pass between the adjacent friction wheels F3. Rotation thus imparted to the egg will be communicated to the Huid within the shell and, when rotation of the shell ceases, the interior uid will continue to rotate. Thus the inspector viewing the ,egg from thc top as illuminated by the light beam will detect any imperfections in the interior of the egg as the uid therein continues its rotation. Every egg on the conveyor F is successively subjected to this inspection and the time interval Vfor passing over the box G is suiciently long .for the careful observation of each. The friction wheels F3 are driven by pulleys F5 on the shafts thereof and belts F6, which in turn are driven by a small electric motor F7 mounted on the frame of the machine.

The advancing row of eggs after .passing the Candler will come into operative relation to the depositing means, but before describing the `latter we will first describe the carton handling means. As above stated, the eggs are usually held in either dozen, two and one-half -dozen or three-dozen lots. The holders for the dozen lots provide two rows of six cells each, while the holders for the three-dozen Alots have six rows of six cells each and are of equal dimensions in length and width. We will therefore describe the mechanism for handling the three-dozen cartons with the understanding that adjustment can be easily made to similarly handle cartons for different numbers of eggs.

Carton conveying means The cartons H are usually formed of cardboard strips having spaced transverse slits therein for cross -engagement with each other to form a series of cells. In vthe three-dozen carton, there are six transversely extending rows H1 of six cells H2 in each row. There is valso a bottom sheet H3 which extends under all of the cells and affords support for the eggs therein. These .cartons are placed in vertical series within a magazine I `from which they are periodically dropped upon a carton conveyor I and are intermittently advanced by the Ylatterfrom row to row. The conveyor I is mounted on a transversely movable carriage K which in turn is mounted on a frame L supporting the magazine I and most .of the mechanism thus far described. This frame includes corner post members L1 and longitudinal and transverse bars connecting the same. The conveyors C and F are mounted on the upper portion of this frame, but the carriage K and conveyor J are at a lower level being moutned primarily on bars or beams L2 which extend in the direction of the conveyors C and F. Cross bars L3 are mounted on the beams L2 and track members L4 are mounted upon and extend transversely of .the bars L3. These track members are grooved along their upper edges to receive balls K1, and the carriage K is provided with bars K2 grooved on their lower edges to engage and rest upon the balls K1. This forms a roller bearing support for the carriage K which permits the latter to move with slight frictional resistance back and `forth on the track members L4. Thejupper -part of the smaller diameter.

carriage K is formed by side channel bars K3 and Across bars K4. There is also a slatted top K5 supported on vthe cross bars K4, which top forms the direct support for the cartons. The conveyor l is formed by endless chains J1 passing around sprockets J2 on shafts J3 located at the forward and rear end of the side bars K. The chains pass around the cross bar l 4 but are below the slatted top K5. However, `bars KG attached to the chains and spaced to receive a carton therebetween pass over the slatted top to move the cartons resting thereon. The arrangement .of the carriage K and conveyor J is such that the cartons can be intermittently advanced longitudinally and 'transversely to successively register the cells -thereof with the point where the eggs are dropped into engagement therewith. Such intermittent movements are effected by the `following mechanism.

Mounted on the frame L is a motor M, which is connected through a reduction transmission M1 with a shaft N rotated at a low angular speed, such as 4 R. P. M. On

the shaft N are pairs of cams O, O1 and P, P1. The cams O and O1 are alternatively used for intermittently actuating the carriage K, the cam O being used for the lling of three-dozen size cartons and the cam O1 for the onedozen. Thus these cams, which are splined to the shaft N, may be .adjusted thereon to bring them alternatively in operative relation with the Acooperating mechanism. The carriage K has secured t0 its underside a pair of spaced .parallel rack bars Q, which engage pinions Q1 on a shaft Q2 journaled in bearings in the track members L4. The shaft Q2 has also a pinion Q3 `thereon which is of smaller diameterand is engaged with a rack bar Q4. The rack bar Q4 has attached to one end thereof a roller Q5 which forms a follower engaging the periphery of one or the other of the cams O, O1. A spring Q5 engaging the rack bar Q4 urges the same ina direction to ymaintain the follower Q5 in contact with the periphery of the cam. The cams are fashioned to impart intermittent movements to the rack bar, which `through the pinion Q3 rotates the shaft Q2, and through the pinions Q1 imparts movement to the rack bars Q and through the latter to the carriage K. By reason of the fact that the pinions Q1 are larger than the pinion Q3, the amplitude of movement imparted to the carriage is greater than that which could be produced by the rack bar Q4 and this permits of using cams of Each of the intermittent movements of the carriage is equal to the dimension between adjacent cells of the carton, and the total number of movements .in one direction is equal to the number of cells in one row of the carton which in the construction illustrated is six but may be any number by a suitable change in earns. After .these six movements, the carriage I is advanced (by means later described) to bring another rowof cells in alignment with the egg depositing point, and the carriage will then be moved in the reverse direction under the actuation of the spring Q6 to perform six more intermittent advancements. This completes the cycle of the cam, which after another movement of the conveyor yrepeats the cycle and so on until all of the cells of the Acarton are iilled. For intermittently actuating the conveyor J lto advance the cartons from row to row, one of `thefshafts J3 has mounted thereon a ratchet wheel R. A rod R1 slidable in bearings on the carriage has attached to one end thereof a pawl R2 engaging the teeth of said ratchet wheel to intermittently rotate the same and, through its shaft and the sprocket wheel thereon, actuate the conveyor. The rod R1 is itself actuated by a lever R3 havingits end ,portion R4 slidably engaging a rod R5 on a rockable member R6, which latter is actuated from one orthe other Vof the cams O and O1 through the medium of a bell -crank lever R7 and connecting rod R8. The rod R5 is of suicient length so that the portion R4 of the lever R3 will remain in engagement therewith in all positions of thecarriage K. Thus after one row of cells has been filled with eggs and the carriage is at that end of. its movement, the yconveyor J is actuated to bring another row in alignment with the depositing means, and when this row is completely lled and the carriage is at the opposite end of its movement, the conveyor is smilarly advanced to bring another row in alignment. However, in passing from one carton to another the space between the cells is somewhat greater as there is a feed bar K between adjacent cartons. The required additional movement is supplied by making the distance between the teeth of the ratchet wheel at one point R9 greater than between the other teeth.

Carton holding magazine The magazine I is open at the top and is of a crosssectional area to receive a stack of cartons, each carton including a cellular portion and a bottom portion. The lowermost carton of the series rests upon fingers I1 which are periodically withdrawn to drop the series to a lower position supported by other lingers I2, after Which the upper lingers I1 are reinserted between the lowermost carton and the next higher one of the series. The lingers I2 are then withdrawn to drop the freed lowermost carton onto the conveyor J. The mechanism for operating the lingers I1 and I2 is illustrated in Figs. 3 and l2 and comprises a pair of rocker members I3 to which the fingers I1 are attached, said rocker members being pivotally mounted upon opposite sides of the magazine I. The rods I4 extend from these rocker members to a bell lever I5 pivotally mounted on a bracket I6 depending from the magazine. Normally the lingers I1 are projected to support the stack of cartons, but a movement of the bell crank lever'I5 to raise the rods I1 will actuate the rockers I3 to withdraw the lingers I1 and permit the stack to drop until movement is arrested by the lingers I2. The latter are preferably formed integral with rocker members I7 similarly arranged on the magazine beneath the rocker members I3 and similarly operated by rods I8 and a bell crank lever I9. Thus after the actuation of the bell crank lever I5, which relieves the lingers I1 and permits the stack of cartons to drop, said lingers will be reinserted beneath the bottom member of the next higher carton. Subsequently, the bell crank lever I9 will be actuated to release the lingers I2 and drop the lowermost carton onto the slatted top of the carriage. The bell crank levers I5 and I0 are'successively actuated by arms I10 and I11 both mounted on the shaft J3 at the forward end of the conveyor I. Once in each cycle of this shaft, these arms will successively actuate the said bell crank levers with the result that a carton is deposited on the carriage. The timing is such that a carton is thus deposited as soon as space is provided by the advancement of a previously de posited carton through the operation of the conveyor J. The mechanism just described is only one specific construction and other means for successively releasing cartons from the mechanism may be substituted therefor.

Egg depositing mechanism The eggs advanced through the Candler as previously described are spaced from each other by the rollers F2 of the conveyor F and thus successively reach the forward end of said conveyor. At this point they are received by the depositing mechanism which is of the following construction. A rotary wheel S is arranged in a plane transverse to the direction of advancement of the conveyor F and is driven from the latter through the medium of bevel gear wheels S1 and S2. The wheel S has mounted thereon a series of egg-holding clamps which are successively registered with the conveyor F to receive an egg therefrom and then carry it around with the Wheel through an angle of 90 to the point where the egg is released and dropped into a cell of the carton. Each of the clamps of the series includes a pair of spaced fingers S3 which, when registered with the conveyor I, will be slightly below the upper portion thereof and opposite the portion passing around the sprocket. This will permit the egg to roll off from its seat between rollers F2 onto the lingers S3, which are slightly concaved on their upper edges at S4. A cooperating linger S5 will then clamp the egg and hold it until it reaches the point for deposit. The linger S5 is on a rock shaft S6 mounted on the wheel S and a spring S7 biases said linger towards clamping position. However, an arm S8 on the shaft S6 engages a cam S0 on a stationary plate S10 and the cam is so positioned that the finger S5 is retracted when the egg is deposited on the lingers S1 and is then released to clamp it. After the wheel S has traveled through an angle of approximately another cam S11 on the plate S10 will release the linger S5 permitting the egg to drop into the registering cell of the carton. In this travel of the wheel the egg is turned so that its major axis, which was horizontal on the conveyor I, is vertical when the egg is released to drop into the cell.

Means for filling gaps in the advancing series of eggs By reason of the fact that the series of eggs passes through the Candler and that some eggs are removed, this would leave gaps in the series which if not lilled would leave certain cells of the cartons unfilled. To avoid such a result we provide mechanism for advancing the series towards the Candler at a faster rate than from there on. Such advancement is by the belts E', E2 and E5 which travel faster than the conveyor F. However, the series on the belts is only frictionally driven and therefore will not advance faster than necessary. Whenever the operator of the candler removes an egg from the conveyor F, which he accomplishes by his right hand, he at the same time uses his left hand to advance the series from the belt E5 over the conveyor F. As the eggs are rotating when passing through the candler 'they can be easily advanced by the slight additional force Automatic gate control The transfer of eggs from the table A is accomplished by the operation of the gate C as has been previously described. It is necessary, however, to control this operation so that eggs will be supplied to the series only as fast as required, which is accomplished as follows. The shaft C of the gate has revolubly mounted on one end thereof a pulley C1 which is connected by a belt C5 with a pulley C0 on the shaft D3 of the endless conveyor D, but this does not necessarily communicate rotation to the shaft C'. The latter is always rotating when the machine is' in operation as is also the belt C5 a'nd pulley C4. Mounted on this shaft in frictional contact with one side of the pulley C1 is a ratchet wheel C7 which, however, is normally held against rotation by a dog C8 engaging one of the teeth of said ratchet wheel. There are four of these teeth equally spaced, and therefore, when the dog is released, the pulley C4, shaft C' and ratchet wheel will be rotated through one-quarter of a revolution turning the gate C the same amount. The dog C0 has a bell crank arm C0 and a solenoid, or other electromagnetic motor C10 when energized will move this bell crank arm to release the dog. Operation of the solenoid C10 is controlled by the eggs on the conveyor E, the arrangement being such that any gap in the series will close a switch energizng the motor. This switch is preferably operated by a light sensitive electric cell T which in turn is operated by a beam of light extending transversely of the conveyor and interrupted by the eggs carried by the conveyor. As shown an electric lamp T' is mounted to project a light beam diagonally across the conveyor E and through an aperture E5 in the rail E4 into the cell T. This beam is, however, interrupted by eggs on the conveyor E, and it is only when there is an open gap that the beam is effective to operate the cell T and through the latter to energize the solenoid C10. Thus Whenever the supply of eggs deposited on the conveyor E is exhausted, the gate will another series on said conveyor. In vthis way the supply of eggs to the Candler and to the depositing .mechanism is lautomatically maintained. VIt is necessary, however, rthat the dog C8 when released from one ratchet tooth vshould be instantly returned to engage the next tooth of 4the ratchet wheel, which is accomplished as follows. The movable core C11 of the solenoid has a link C12 4pivotally attached thereto and the lower end yof this link .has a pin C13 for engaging the bell crank arm C9 to release `the dog. However, an `extension of the pin C13 engages an inclined track C1'1 so that in the further upward movement of the core C11 the pin will be disengaged from the arm C9. This permitsthe arm to drop thereby re-engaging the dog with the ratchet wheel when the solenoid is de-energized andthe core Y drop the pin C13 engaging an inclined end C15 of .the arm C9 will be deflected to pass beneath the -other so as ,to be in position for another operation.

Operation From, the description above, the operation of the machine will be understood, but ,it may be briefly restated as follows. Eggs traveling on the conveyor A are `transferred therefrom by the inclined bar A2 to the table ,A

be operated to deposit C11 and link C12 on top of the ilexible cover B. The traveling conveyor,

.D beneath the cover B will cause the advancement of the eggs over the table towards the gate C, but the force exerted is not sufficient to endanger breakage. The gate is operated by the mechanism above described whenever there is a gap in the series of eggs on the conveyor E to transfer ,another row of eggs from the table A onto said conveyor. The latter will advance the series to the conveyor F, which carries them through the Candler. The hour glass shaped rollers F2 of the conveyor F are intermittently rotated by passing over the friction wheels F3 which are in constant rotation, being driven by the motor F7, pulleys F5 and belts F6. Thus as the eggs pass over the light beam from the light bulbsgG in the box G, they are inspected and when they are bad are removed from the series. The gap is then refilledby the inspector, who

manually advances the series over the rollers F2. At the 4end of the conveyor F, the eggs are successively transferred to the clamping holders on the wheel S andare carried thereby into position for dropping `intothe .cells of the cartons. During this transfer `the long-axis of .the

egg is changed from horizontal to vertical, and the clamping and unclamping of the holdersi's .eiected by cams on the stationary plate S10. The cartons stacked in the magazine l are successively dropped therefrom onto the carriage K and are intermittently advanced longitudinally thereover by the conveyor l. Such advancement is only from row to row of cells yin `thecarton `while the step by step transverse movement ofthe carriage successively registers the cells in each row with the egg dropping point. In this manner all of the cells in each carton are filled with eggs and the lled cartons `are delivered from the rear end of the carriage. The mechanism for effecting these movements has been previously fully described and it is unnecessary to repeat the description of the same.
